Mycoplasma-free PV and SAD/ERA Virus Stocks for Rabies Vaccine Manufacturing

This technology includes mycoplasma-free PV (isolated in 1882) and SAD/ERA (isolated in 1935) virus stock for rabies vaccine development. Rabies virus causes a nearly uniformly fatal disease, but can be prevented by timely vaccination. Two of the most common rabies virus vaccine strains are PV and SAD/ERA, both of which have had extensive passaging in both animals and subsequently cultivation in cells. The rabies vaccine virus stocks stored at CDC are heavily contaminated by mycoplasma.

Identifying Inhibitors of Highly-pathogenic Arenaviruses Through Minigenome and Recombinant Virus Reporter Systems

This technology includes a novel minigenome assay for arenaviruses that allows for high-throughput screening (HTS) of potential antiviral compounds. To complement to minigenome assay, we have also developed a technique to generate recombinant arenaviruses expressing a reporter protein to allow to HTS of antiviral compounds at BSL-4. This allows for confirmation of potential hits identified by the initial minigenome screen. Human infections with some Arenaviruses such as Lassa (LASV) and Junin (JUNV) virus can result in viral hemorrhagic fever (VHF) disease.

Real-time RT-PCR Assay for Detection and Characterization of North American Lineage of A/H7 Influenza Viruses

This technology includes an updated North American Lineage H7 (N.A H7) real-time RT-PCR assay is designed for specific detection and characterization of North American lineage of A/H7 influenza viruses. Since 1995, poultry infection with N.A lineage influenza A/H7 viruses has been greatly increasing. The outbreaks of N.A A/H7 viruses in poultry as well as wild birds occurred many times in Canada, Mexico and USA; meanwhile a number of human infection caused by N.A A/H7 viruses have been confirmed following exposure to infected poultry.

Real-Time RT-PCR Diagnostic Panel Assay for Universal Detection and Characterization of Asian Lineage Highly-Pathogenic Influenza Viruses A/H5 Subtype

This technology includes an optimized influenza A/H5 subtyping real-time RT-PCR assay for detection and characterization of Asian lineage A/H5N1 viruses. The highly pathogenic avian influenza (HPAI) A/H5N1 viruses, first isolated in human in 1997, have spread among birds over seventy countries on three continents. In 2014 a novel reassortant HPAI A/H5N8 virus has been detected in poultry in Asia, Europe, As well as Canada and USA. In addition, genetic reassortment of this virus with circulating avian influenza viruses has resulted in the novel viral combinations.

Virus isolation of the Florida strain of MERS-CoV for Anti-viral Research, Diagnostic and Vaccine Development

This technology includes isolate of Middle East respiratory syndrome coronavirus (MERS-CoV) for antiviral and diagnostic development. The isolate was confirmed by full genome sequencing and further characterized by serologic and molecular testing and electron-microscopical studies. This is the first MERS-CoV strain isolated from a US imported case of MERS.

Combination Dosing Regimens for the Prevention of HIV

This technology includes combinations of currently approved antiretrovirals (ARVs) which could allow for simpler dosing regimens that improve adherence to HIV prevention strategies. Event-Driven PrEP (ED-PrEP) with 2 oral doses of tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) taken 2-24 hours before sex, a 3rd dose 24 hours after sex, and a 4th dose 48 hours after sex (2+1+1) is considered as a PrEP option by the World Health Organization for men who have sex with men (MSM). Recommended post-exposure prophylaxis (PEP) regimens require 28 days of daily oral dosing.
